For the question what SJR is, Wikipedia (yeah!) helped me a lot: http://en.wikipedia.org/wiki/SCImago_Journal_Rank
A bigger problem is the general recognition of impact factors of whatever kind - at least here and now (that is, sociology in Germany), noone of the "established" (t.i. university professor) accepts any kind of impact factor, always putting the individual quality of an article first. Well, that is not so useful for younger academics...
Thanks Philipp. I think the issue of impact factor should be reconsidered. Individual qualities of papers should be used to judge researchers and their output.
SCImago Journal Rank (SJR) is different of JCR impact factors. The last is a very simple and plain ratio between documents and cites. Each cite has the same weight. In SJR they implement a more complex formula based in the well know Page Rank algorithm. In the weight of the cite depends on the prestige of the citing journal.
SCImago Journal Rank (SJR) and Source Normalized Impact per Paper (SNIP) 2016 values
In addition to finding the new CiteScore values on both the Scopus Source details page and journalmetrics.scopus.com, also look for the newly released SJR and SNIP 2016 values...
CiteScore metrics from Scopus are comprehensive, transparent, current and free metrics for serial titles in Scopus. Search or browse below to find a source and see associated metrics. Use the annual metrics for reporting, and track the progress of 2017 metrics with CiteScore Tracker 2017. Be sure to use qualitative as well as the below quantitative inputs when presenting your research impact, and always use more than one metric for the quantitative part...
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact. (Elsevier)
The SCImajo journal rank is a scientific research rank for impact articles. It comes with ranks per journal index on several other pages. It ranks as per countries citation, self citations, but largely based on impact factor. There are several journal on SJR, inter alia, Taylor and Francis, Wiley, Elsevier, Emerald and many more.
